What is Melanotan II?
Melanotan II (MT-II — synthetic alpha-MSH analog) is a 7-amino acid cyclic lactam peptide. Synthetic alpha-MSH analog activating MC1R (melanogenesis — skin pigmentation, UV photoprotection) and MC4R (appetite suppression, energy balance, sexual function). Broader melanocortin receptor profile than selective MC1R agonists, with both peripheral pigmentation and central appetite/sexual function effects.
Research Applications
MC1R Melanogenesis
Eumelanin production, UV photoprotection, pigmentation biology
MC4R Central Effects
Hypothalamic appetite suppression, energy balance via MC4R
Sexual Function
Central MC4R-mediated sexual arousal and function pathways
Melanocortin Selectivity
MC1R + MC4R dual vs selective receptor comparison
Skin Biology
Pigmentation research, melanocyte activation, photoprotection
